' and has for itsobjectto provide new and improved constructions in devices ofl that class. Theinvention is illustrated in the accomf panying drawings wherein A Figure 1l is. an end. view of a carpet sweeper with parts broken away 5 Fig. 2, a plan view of a portion of the end; Fig. 3,l an inverted plan view of the same; Fig. 4, a plan viewof the inclosing shieldfor the wheels from below and removed from the case; Fig. 5, a section on line 5--5 of Fig.l1 Fig.f6,.a plan view of a modification; Fig. 7, an end view ofthe same with parts broken away; Fig. 8, a sectional view on line 8--8 of Fig. 6, and Fig. 9, a sectional view on line 9 9 of Fi 7.

Like letters of reference indicate like parts in all the drawings.

The invention relates particularly to means for mounting, protectlng and incasing the mechanisms of the sweeper at one or each of its ends, and which mechanisms are likely to become clogged with dirt when exposed in an of the customary ways or otherwise init of metal.

jure to the detriment of the operation of the sweeper.

In the drawings, A represents the casing which may be of any desired type, either of metal or of wood, although Ivprefer to make y Thiscasing has within 'it the brush roll B of any 'desired sort and is partially closedv at the bottom by the dust pans C C. At one oreach end, of the casing A, I construct a housing forming a chamber in which are contained the various mechanisms customarily located at the ends of carpet -sweeper casings, such as the wheels, their r thebrush pulley, and the like. By my lnventlon,` these parts are com-` mountings,

pletely separated from the dust chamber of t e sweeper and are inclosed in a chamber by-themselves so that they are kepto practically free from dirt and other matter liable lto clog them in their operations. This chamber is inclosed o n all sides'but provided with apertures through which certain parts ex- -Specicationof Letters Patent.

tend. As here shown, 'this chamberl is formed by the end piece D of the sweeper casing, to which is secured an inclosing orend casmg E having its ends' turned over to form the flange E1 whichl is apertured on the under side at E2 E2 for the sweeper wheels and provided with lugs E3 adapted to extend into slots E1 in the end piece D. The end casing E is held in position by means of the screw E5 rivetedto the end pieceand extending through a hole in the part E. and the' The endpiecev is apertured thumb'nut E". for the brush roll B, as for example, by the Patented oct. 6,:19os;* y

mechanisms above referred to are mounted Within the chamber in any desired manner; for example, the inclosing'` casingfE is provided'with the pivot Friveted thereto and which extendsinto -a perforation F1 iny the pulley B1 on the brush roll-B.y u Y.

' The wheels are (preferably mounted on 'the spindles G, carrie by the rock arms Glxpivoted at Gzto the end piece D. The wheel maybe held yieldingly against the pulley B1 t by means of a spring G3 secured to the casing at G1 G4 and pressing against a pin G5 on the arm G1, as shown on the left hand side of Fig. 1. l l

The sweeper is operated in the usual manner by means of the handle H having the bail H1 extending into each end of the case through apertures H2. .The end casing E is preferably formed so as to extend across the aperture H2, the material at this point being struck down as indicated at H3 so as to form This pocket holds the end of the bail in osition in the case against the tendency of the .l bail, especially when made of springy material,` to spread under pressure from the handle.

Figs. 6 to 9 inclusive are-views of a similar construction of car etsweeper but presenting certain modi cations. The material forming the end D of the case is stamped or ystruck downat D2 D2 and in these sunken "portions are located the arms G1 G1 on which the wheels are mounted in the manner described in the other form of sweeper. The arts G1 G1 are, in this instance, slotted at 6 Gr so as to give the said arms sliding move` ment up and down on the pivots G2 G2. The end of the case D .has the erforations D3 D3 Within the sunken parts 2D2 and a single or otherwise.

spring J coiled about the post J1 on the inside of the end iece D presses ateach end against the posts 2 J2 riveted to the arms G5 G5 and extending through the apertures D3. By this construction the sweeper has broom action; that is, when pressure is put upon the handle in operation, the casing will be carried downward and the bristles of the brush Jforced against the surface being swe t. The bearing parts of the wheel, as it wi be seen, are incased in pockets formed by the sunken portions DZ D2.

The use and operation of my device are as follows: One of the principal aims of my invention is to so incase or house the end mechanisms of the sweeper that there will be no chance for them to become clogged up from dust, threads, ravelings, etc. either from the action ofthe broom Within the dust chamber According to the arrangements and devices above shown, these arts are com letely removed from the dust c amber an efficiently shielded andl rotected from dust or the like which might e carried up into the bearings from the floor. By this arrangement .the possibility -of clogging is very largely if not entirely done away with.

In the form shown, the chamber or housing is of very sim le construction, consisting of a flange piece secured to the end of the easing, `and which may be quickly removed if need be, by removing the thumb nut E".

Iclaim:

1.V In a carpet sweeper, the combination of a sweeper case with a bail extending into a hole in the end of the case, wheels mounted on the outside of the end of the case, and a flan i ed shield coveringy a portion of the end of t e case and provided with a depression in the upper side of the flange thereofinto which the bail extends so as to maintain the end thereof in engagement with the end of the case.

2. In a carpet sweeper7 the combination of a sweeper case, with wheels mounted on the outside of the end of the case, a brush roll extending through an openin in the end of the case, a pulley on the end o the brush roll having a erforation in the end thereof, a flanged shield covering the wheels and brush roll pulley and provided with apertures throu h which thev wheels extend, a pivot on said shield extending into thel perforation in .the brush roll pulley, abail pivoted'to the end of the casing, the upper flange of said ilanged shield being provl ed with a depression into which the end of the bail extends, and means for securing the shield to the end of the case.
